This is our Pollenc stemmer from France. There are very few in the valley.

The grapes are gently seperated from their stems and as they pass over the rollers fall through the spaces between to a moving conveyor belt while the stems ride above to a tray at the end where an augur pushes them into a picking box.

It is important not to damage the skins – they give color, tannin and more to the wine but it is equally important not to damage the stems as the flavors that might be extracted are not good – on the green side. Bite into one and you can imagine.
